Switch to using WebIntentPickerModel, and bring picker closer to mocks.

Can you move this three down? Then you don't need to call lastObject twice, you
can just do

  ASSERT_TRUE([button isKindOfClass:[NSButton class]]);

(Casting to NSButton* before asserting this looks a bit funny, but is fairly
common in our code, and isn't wrong.)
